Compiling RTEMS 4.9.5 on Cygwin, needed to remove -Werror



Hi to all,

Just to report something I've seen: while compiling gdb for RTEMS 4.9.5 on 
Cygwin (latest version 1.7.x) I had this error (it was for arm target but I 
had the same problem for other targets):

gcc -c -g -O2   -I. -I../../gdb-6.8/gdb -I../../gdb-6.8/gdb/config -DLOCALEDIR="\"/cygdrive/p/Antoine/tools/armtools/share/locale\""

make[2]: *** [remote-fileio.o] Error 1

I confirm that the cygwin.h line above announces in its comments that this 
is a deprecated primitive.
Just removing -Werror option in the Makefile (in gdb directory) solves the 
problem and the compilation goes till the end.
